At least since KDE 3.5 (didn't ever try in earlier Versions), suspending a notification message for 30 days makes it pop-up immediately and keeps popping up.

Steps to reproduce:
1. Schedule a new appointment to trigger at now+n minutes (n > 0) and check reminder at 0 minutes.
2. Wait for notification
3. Select 30 days for "suspend duration"
4. Hit "Suspend"

Expected results:
Nothing.
After 30 days, notification should pop up

Actual results:
Notification pops up immediately.
Hitting Suspend makes it pop up immediately again.
Hitting Suspend makes it pop up immediately again.
...
This goes on for some iterations before the popup finally vanishes. I can't yet tell whether the suspend will actually trigger a proper popup after the actually set duration has passed. I'll report back after 30 days.
